I made this out of an apple juice bottle with a stem from a broken bong. The stem is snug and the bottom hole is pretty nice. Rate it?
no need for the full stem, just make the hole a bit bigger and unscrew the bowl and put it in there, and might want to put the hole a bit lower, but waterfall bongs are amazing for homemade pieces and pack a powerful punch, you should greatly enjoy it.
that bottle is pretty big for a waterfall and it should get you really blazed. +1 on a lower hole. just so you dont have to tip the bottle a bit to get that last bit of water out.
Put the hole on the very bottom you dont want water left after when you pull all that smoke through. Other than that creative and nice and I love apple juice.
